The level of digoxin for treatment is typically 0.5-2 ng/mL. [8] Since this is a narrow therapeutic index, digoxin overdose can happen. A serum digoxin concentration of 0.5-0.9 ng/mL among those with heart failure is associated with reduced heart failure deaths and hospitalizations. [9]
Digoxin increased the risk of death in women by 23%. There was no difference in the death rate for men in the study. [38] Digoxin is also used as a standard control substance to test for P-glycoprotein inhibition. [39] Digoxin appears to be a peripherally selective drug due to limited brain uptake caused by binding to P-glycoprotein. [40] [41]
Other oculotoxic effects of digoxin include generalized blurry vision, as well as seeing a "halo" around each point of light. The latter effect can also be seen in van Gogh's 1889 painting The Starry Night. Evidence of van Gogh's digoxin use is supported by multiple self-portraits that include the foxglove plant, from which digoxin is obtained ...

For example, in 2008 US poison centers reported 2,632 cases of digoxin toxicity, and 17 cases of digoxin-related deaths. [18] Because cardiac glycosides affect the cardiovascular, neurologic, and gastrointestinal systems, these three systems can be used to determine the effects of toxicity.

1] The drug digoxin is an example of this type of drug. [29] Risks are also increased when the drug presents a steep dose-response curve, and small changes in the dosage produce large changes in the drug's concentration in the blood plasma. [29]
A drug overdose (overdose or OD) is the ingestion or application of a drug or other substance in quantities much greater than are recommended. [2] [3] Typically the term is applied for cases when a risk to health is a potential result. [2] An overdose may result in a toxic state or death. [3]
